    Class JadeExportExtendedPublicKey

    Base class for direct keystore interactions.

    Subclasses must implement a run method which communicates directly with the keystore. This method must be asynchronous (return a Promise) to accommodate delays with network, devices, &c.

    import {DirectKeystoreInteraction} from "@caravan/wallets";
    class SimpleDirectInteraction extends DirectKeystoreInteraction {   *

      constructor({param}) {
        super();
        this.param = param;
      }

      async run() {
        // Or do something complicated...
        return this.param;
      }
    }

    const interaction = new SimpleDirectInteraction({param: "foo"});

    const result = await interaction.run();
    console.log(result);
    // "foo"

    Methods

    • Subclasses can override this method to indicate they are not supported.

      This method has access to whatever options may have been passed in by the constructor as well as the ability to interact with this.environment to determine whether the functionality is supported. See the Bowser documentation for more details: https://github.com/lancedikson/bowser

      Returns boolean

      isSupported() {
        return this.environment.satisfies({
          * declare browsers per OS
          windows: {
            "internet explorer": ">10",
          },
          macos: {
            safari: ">10.1"
          },

          * per platform (mobile, desktop or tablet)
          mobile: {
            safari: '>=9',
            'android browser': '>3.10'
          },

          * or in general
          chrome: "~20.1.1432",
          firefox: ">31",
          opera: ">=22",

          * also supports equality operator
          chrome: "=20.1.1432", * will match particular build only

          * and loose-equality operator
          chrome: "~20",        * will match any 20.* sub-version
          chrome: "~20.1"       * will match any 20.1.* sub-version (20.1.19 as well as 20.1.12.42-alpha.1)
        });
      }

    • Return messages filtered by the given options.

      Multiple options can be given at once to filter along multiple dimensions.

      Parameters

      • __namedParameters: MessageMethodArgs

      Returns Message[]

      import {PENDING, ACTIVE} from "@caravan/bitcoin";
      // Create any interaction instance
      interaction.messages().forEach(msg => console.log(msg));
        { code: "device.connect", state: "pending", level: "info", text: "Please plug in your device."}
        { code: "device.active", state: "active", level: "info", text: "Communicating with your device..."}
        { code: "device.active.warning", state: "active", level: "warning", text: "Your device will warn you about...", version: "2.x"}
      interaction.messagesFor({state: PENDING}).forEach(msg => console.log(msg));
        { code: "device.connect", state: "pending", level: "info", text: "Please plug in your device."}
      interaction.messagesFor({code: ACTIVE}).forEach(msg => console.log(msg));
        { code: "device.active", state: "active", level: "info", text: "Communicating with your device..."}
        { code: "device.active.warning", state: "active", level: "warning", text: "Your device will warn you about...", version: "2.x"}
      interaction.messagesFor({version: /^2/}).forEach(msg => console.log(msg));
        { code: "device.active", state: "active", level: "warning", text: "Your device will warn you about...", version: "2.x"}

    • Initiate the intended interaction and return a result.

      Subclasses must override this function. This function must always return a promise as it is designed to be called within an await block.

      Returns Promise<string | { rootFingerprint: null | string; xpub: string }>
